Description

Technical Field

[0001] The present invention relates to the technical field of vehicle parts, and particularly relates to a tolerance adjuster, a hidden door handle and a vehicle. Background Art

[0002] In the automotive field, a tolerance adjuster is used to automatically compensate for the cumulative tolerance between the door handle installation point and the body-in-white stamping and welding of the vehicle door. Without using a tolerance adjuster, it is necessary to repeatedly check the gap and surface difference between the handle and the outer body-in-white during installation.

[0003] In the related prior art, a tolerance adjuster generally includes an adjusting member and a fastening member. A through hole is formed at the bottom of the adjusting member. When the tolerance adjuster is assembled, the tail of the fastening member passes through the through hole and is connected to the target member, so that the adjusting member can be fixed. However, the fastening member relies on the friction angle of the thread surface to achieve self-locking. When the vehicle is running and generating continuous high-frequency vibrations, a small amplitude of reciprocating slip occurs between the thread pairs, resulting in the attenuation of the friction coefficient and the gradual loss of the pre-tightening force, making the fastening member prone to axial retraction, thus leading to assembly failure. Summary of the Invention

[0004] Based on the above description, the present invention provides a tolerance adjuster, a hidden door handle and a vehicle, aiming to solve the problem that the fastening member of the existing tolerance adjuster is prone to axial retraction under vibration conditions.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: In a first aspect, a tolerance adjuster includes: An adjusting member having a through hole; A fastening member, the tail of which passes through the through hole; An anti-detachment mechanism including a baffle and a plurality of limiting components. The baffle is arranged inside the adjusting member and is parallel to the head of the fastening member. There is a distance between the baffle and the bottom wall of the adjusting member. The plurality of limiting components are arranged at intervals along the circumference of the baffle. The baffle is connected to the adjusting member through the plurality of limiting components.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Further, the distance between the anti-detachment component and the bottom wall of the adjusting member is configured to be 3 mm to 5 mm.

[0008] Further, a support protrusion is provided on the inner side wall of the adjusting member. The baffle is arranged on the support protrusion. The limiting component includes a first card slot, a step and a limiting plate. The first card slot is formed on the baffle. The first card slot has an installation side wall. One end of the step is connected to the installation side wall. The limiting plate is connected to the adjusting member and corresponds to the first card slot. The limiting plate abuts against the step.

[0009] Furthermore, a limiting protrusion is provided on the abutting surface between the step and the limiting plate.

[0010] Furthermore, a side of the limiting protrusion facing away from the mounting side wall and a side of the step facing away from the mounting side wall are jointly constructed to form an inclined surface.

[0011] Furthermore, the limiting assembly includes a hook and a second slot, the hook is arranged on the baffle, the second slot is opened on the inner side wall of the adjusting member, and the second slot corresponds to the hook.

[0012] Furthermore, a socket is provided in the second card slot.

[0013] Furthermore, the second slot is configured to be L-shaped.

[0014] In a second aspect, a hidden door handle comprises the tolerance adjuster according to the first aspect.

[0015] According to a third aspect, a vehicle comprises the hidden door handle according to the second aspect.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: (1) The present invention can prevent the fastener from axially retreating by means of the baffle, and the limit assembly can disperse the vibration load, thereby preventing the fastener from separating from the adjusting member.

[0017] (2) When the baffle of the present invention is placed on the supporting protrusion, the limit plate is first located in the first slot, and the baffle is rotated at the same time so that the step and the limit plate abut against each other to prevent the baffle from radial displacement. This makes it easier to disassemble and position the baffle, thereby improving work efficiency.

[0018] (3) In the present invention, when the hook slides to the end of the second slot, the hook cooperates with the first slot to complete the locking. This not only facilitates the connection between the baffle and the adjusting member, but also facilitates the positioning of the baffle, so that the baffle and the bottom wall of the adjusting member maintain a corresponding distance.

[0022] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

It should also be understood that terms such as "comprising" or "having" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0026] Referring to Figures 1 to 2 、 Figures 4 to 5 and Figure 8 As shown, the present invention provides a technical solution: a tolerance adjuster, comprising an adjusting member 10, a fastening member 20 and an anti - detachment mechanism 30. The adjusting member 10 has a through - hole 11; the tail of the fastening member 20 passes through the through - hole 11; the anti - detachment mechanism 30 includes a baffle 31 and a plurality of limiting components 32. The baffle 31 is arranged inside the adjusting member 10 and is parallel to the head of the fastening member 20. There is a spacing between the baffle 31 and the bottom wall of the adjusting member 10. The plurality of limiting components 32 are arranged at intervals along the circumferential direction of the baffle 31. The baffle 31 is connected to the adjusting member 10 through the plurality of limiting components 32.

[0027] In this embodiment, after the tolerance of the adjusting member 10 is adjusted, the fastening member 20 is screwed into the target member, and then the baffle 31 is placed inside the adjusting member 10. The baffle 31 is connected to the adjusting member 10 through the limiting components 32, so that the baffle 31 converts the axial force into a radial constraint on the side wall of the adjusting member 10 through the limiting components 32, forming a two - way lock. In this way, the baffle 31 can prevent the axial retraction of the fastening member 20, and the limiting components 32 can disperse the vibration load, thereby preventing the fastening member 20 from detaching from the adjusting member 10.

[0028] In some embodiments, the spacing between the anti - detachment component and the bottom wall of the adjusting member is configured to be 3 mm to 5 mm.

[0029] In this embodiment, by reserving sufficient spacing, it is ensured that the adjusting member 10 has enough space to adjust the tolerance.

[0030] The following is an example of the limiting component 32.

[0031] Embodiment 1 Refer to Figures 1 to 4 As shown, in some embodiments, a support protrusion 12 is provided on the inner side wall of the adjusting member 10, the baffle 31 is disposed on the support protrusion 12, the limiting component 32 includes a first card slot 3211, a step 3212 and a limiting plate 3213. The first card slot 3211 is opened on the baffle 31. The first card slot 3211 has an installation side wall. One end of the step 3212 is connected to the installation side wall. The limiting plate 3213 is connected to the adjusting member 10, and the limiting plate 3213 corresponds to the first card slot 3211, and the limiting plate 3213 abuts against the step 3212.

[0032] In this embodiment, the support protrusion 12 plays a supporting role for the baffle 31 to ensure that there is a corresponding spacing between the baffle 31 and the bottom wall of the adjusting member 10. In addition, the support protrusion 12 can bear static load and reduce the shear stress of the limiting component 32. When the baffle 31 is placed on the support protrusion 12, the limiting plate 3213 is first located in the first card slot 3211. At the same time, the baffle 31 is rotated so that the step 3212 abuts against the limiting plate 3213 to prevent the radial displacement of the baffle 31. In this way, the disassembly, installation and positioning of the baffle 31 can be facilitated, thereby improving the work efficiency.

[0033] Refer to Figure 3 As shown, in some embodiments, a limiting protrusion 32121 is provided on the abutting surface between the step 3212 and the limiting plate 3213.

[0034] In this embodiment, the limiting protrusion 32121 plays a limiting role for the limiting plate 3213, which can further prevent the radial displacement of the baffle 31 and ensure that the limiting plate 3213 is not easily separated from the first card slot 3211.

[0035] Refer to Figure 3 As shown, in some embodiments, the side of the limiting protrusion 32121 facing away from the installation side wall and the side of the step 3212 facing away from the installation side wall are jointly configured as an inclined surface.

[0036] In this embodiment, when the baffle 31 is rotated, the inclined surface can guide the limiting plate 3213 to smoothly slide into the clamping area formed by the step 3212 and the limiting protrusion 32121, avoiding strong friction force generated by the limiting protrusion 32121 on the limiting plate 3213.

[0037] Embodiment 2 Refer to Figures 5 to 8As shown, in some embodiments, the limit component 32 includes a hook 3221 and a second card slot 3222. The hook 3221 is provided on the baffle 31, and the second card slot 3222 is formed on the inner side wall of the adjusting member 10, and the second card slot 3222 corresponds to the hook 3221.

[0038] In this embodiment, during the process of placing the baffle 31 on the adjusting member 10, the hook 3221 slides along the second card slot 3222. When the hook 3221 slides to the end of the second card slot 3222, the hook 3221 generates frictional resistance with the first card slot 3211 to complete the locking. In this way, not only can the connection between the baffle 31 and the adjusting member 10 be facilitated, but also the positioning of the baffle 31 can be facilitated, so that the baffle 31 maintains a corresponding distance from the bottom wall of the adjusting member 10.

[0039] Refer to Figure 6 As shown, in some embodiments, a jack 32221 is formed in the second card slot 3222.

[0040] In this embodiment, when the hook 3221 slides to the end of the second card slot 3222, the hook portion of the hook 3221 is inserted into the jack 32221, thereby realizing the fixation of the hook 3221 and the positioning of the baffle 31.

[0041] In other embodiments, the second card slot 3222 is configured in an L shape.

[0042] In this embodiment, when the hook 3221 slides to the end of the second card slot 3222, the baffle 31 is rotated to make the hook portion of the hook 3221 enter the horizontal section of the second card slot 3222, thereby realizing the fixation of the hook 3221 and the positioning of the baffle 31. Such a setting can make the disassembly and assembly of the baffle 31 more convenient.

[0043] The present invention provides a technical solution: a hidden door handle, including the above-mentioned tolerance adjuster.

[0044] The present invention provides a technical solution: a vehicle, including the above-mentioned hidden door handle.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
